PGR Series

Specifically Designed For Golf Range & Outdoor Hospitality Applications

  • Seven input sizes from 40,000 BTU/HR to 125,000 BTU/HR
  • Vented and indirect vented operation.
  • Emitter Tubes are all calorized steel for higher radiant efficiency and
    corrosion resistance.
  • Emitter tube terminates inside the reflector body and the products of combustion are
    discharged under the reflector body to increase the return tube temperature and improve overall efficiency.
  • No exposed exhauster motors. The blower is enclosed inside the burner box for quieter system operation and less maintenance.
  • Two Point Tube Suspension System with external frame brackets to minimize
    assembly & installation time.

Unvented or Vented Application 

The PGR series heater offers maximum flexibility in hospitality and golf range applications. This range of heaters can provide warmth in the windiest conditions and will blend into the surroundings. The decorative grill provides an aesthetically appealing look that will please any building owner. 

Vented application requires Vent Kit (Part#44622000).

Indicate model number based on Btu/hr input (e.g., 100,000 Btu/hr), total emitter length, (e.g., 30 feet) and gas type (e.g., natural gas single stage input). The unit selection for a straight tube
would be PGR100-30-N5, *MOUNT HEATERS AS HIGH AS POSSIBLE. Minimums are shown for indoor applications as a guideline for human comfort and uniform energy distribution.
For outdoor applications heaters can be mounted lower. Consult your Space-Ray representative for the particulars of your installation requirements.

▲WARNING: Certain materials or objects, when stored under the heater, will be subjected to radiant heat and
could be seriously damaged. Observe the Minimum Clearances to Combustibles listed in the manual and on the
heater at all times.

COMBUSTION AIR AND VENTILATION

Combustion air and venting requirements for all gas-fired heating equipment must be provided per the National Fuel Gas Code NFPA54 or the authority having jurisdiction Heaters can be vented, indirect vented or unvented. Refer to the Installation and Operation Instructions for further information. A vented installation must be vented to the outside of the building with a flue pipe. In indoor and tightly sealed buildings this heater requires ventilation. An Indirect vented installation requires a minimum ventilation flow of 4 CFM per 1000 Btu/hr of total installed heater capacity on natural gas by either gravity or power ventilation,

INSTALLATION REQUIREMENTS

Installation and service must be performed by a licensed contractor. The installation must conform to written Instalation & Operating Instructions and local codes. In the absence of local codes, the installation must conform with the National Fuel Gas code, ANSI Z223.1 (latest edition also known as NFPA54) or GCA B149 (latest edition) installation codes. These codes are available from the National Fire Protection Association, Inc., Batterymarch Park, Quincy, MA 02269 or the Canadian Gas Association, 55 Scarsdale Road, Toronto, Ontario M3B 2R3, CANADA.

FOR YOUR SAFETY

Operate infrared heaters with proper care and observe all safety precautions. Carefully follow printed installation, operating and cleaning instructions furnished with the heater. Do not store gasoline or combustible products in the vicinity of the heater. Do not touch the heater or the tubes while the heater is in operation. Adequate ventilation must always be provided in accordance with codes.

The stated clearance to combustibles represents a surface temperature of 90 ºF (32 ºC) above room
temperature. Building materials with a low heat tolerance (such as plastics, vinyle siding, canvas, tri-ply, etc.)
may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent
materials are protected from degradation.
